vlanCMMIPv6AddressPrefixLen
Module: CME-MIB
OID (symbolic): CME-MIB::vlanCMMIPv6AddressPrefixLen
OID (numeric): 1.3.6.1.4.1.2.3.51.2.4.9.1.20.20.1.72
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: This object sets the IPv6 address prefix length for this VLAN entry.
The entry with the vlanCMMIndex value of 1 (default VLAN entry) will have this object set to the IP address of the ethernet interface. The IP address of the default VLAN entry can only change by changing the IP address of the ethernet interface.
For all other VLAN entries, this object may be set to any IP address except the IP address of the ethernet interface.
For a change of this object to take effect, the object, vlanCMMState, must be set to enable(1) if the vlanCMMState is currently disable(0), or set to restart(2) if the vlanCMMState is currently enable(1).
What is vlanCMMIPv6AddressPrefixLen?
This writable object sets the prefix length (0-128) that accompanies the VLAN entry's IPv6 address, and like the address itself is tied to the Ethernet interface for the default VLAN. The prefix length determines how much of the address the MM treats as the local subnet versus routed elsewhere, so setting it wrong on a custom VLAN would misjudge which peers are on-link. An admin assigning fd00::10 to VLAN entry 4 would typically set this to 64 to match a standard /64 IPv6 subnet.
